Tensile Tests of Films

Standard No. ISO527-3: 2012 (JIS K 7127: 1999)

Introduction

Tensile tests are widely used to evaluate plastic materials, and the results are used as indices for new materials development and for implementing quality control. Items widely evaluated as tensile characteristics of plastic materials include the tensile modulus, strength, and break strain. 

 

In this Data Sheet, break strain was measured based on displacement data acquired using an extensometer. 

The strength was also evaluated.

 

Measurements and jigs

Non-contact type extensometers capable of displacement measurements without affecting the sample properties are effective for accurately measuring the break strain of a film. In measuring such physical properties, the sample must be gripped evenly, suppressing the occurrence of wrinkles, so it is important to choose the grips carefully. 

As in this test, the use of a non-contact type extensometer/width sensor and foil grips is recommended for film tensile tests.
